Too much fuel

[AMGeneral]

Boy,I got lucky,found out that I had my Deuce fuel rate turned up as far as it would go(24 flats or 4 complete turns)lucky I didn't blow it up!I didn't realize I had it turned up that far,It did run quite good though.It just obscured the road behind me unless I was shifting gears.

Do you have a pyrometer? Wonder what kind of temps it was producing.....

When my pump was turned up too much, it would max the pyro at 1400 degrees. Only did it once, and adjusted down the next day. Makes a great smoke screen.

Aprox how many threads are exposed past the nuts at max fuel?

 

[AMGeneral]

Approx 1/2 inch of threads past the nuts,but I had turned the adjustment till it stopped turning.It did throw out quite a smokescreen,totally obscured the road behind me.I don't have a pyro on my deuce so I have no idea of the temp of the exhaust.

I'll give you a hint - with the fuel turned up all the way, on a hard run your EGTs are in the range that will melt your turbo. INSTALL A PYROMETER, then crank the fuel down to a safe level, no more than 1100-1150F on a hard pull unless you want to buy a new turbo. If you can't afford/can't install a pyro, turn down the fuel until you get a light plume of smoke when you upshift and then no more smoke when you get in the 1800-2000 rpm range. Any more fuel than that and you WILL eventually fry your turbo!

Note that EGTs are dependent on ambient temperature. I have noticed my EGTs have dropped 50-100F from summertime to fall temperatures (well maybe winter time temps, we've already had an 8" snowfall out here, night time temps fall to the mid 20s, but REAL wintertime lows are about 0F out here in western Michigan). But I use an electronic pyrometer which corrects EGT based on ambient temps vs a mechanical pryo which assumes an ambient temp of 70F.
